Top Gameplay-Related Castle Upgrades

Orb structures for summoning heroes

One of the most important castle upgrades in Fire Emblem Heroes is the installation of orb structures. These structures are essential for summoning new heroes to join your army. Each orb structure provides a certain number of orbs every day, allowing you to accumulate a significant amount over time.

By having multiple orb structures in your castle, you can increase your daily orb income and have a better chance of summoning powerful heroes for your team.

Tactics Room for barracks expansion

The Tactics Room is another crucial castle upgrade that every Fire Emblem Heroes player should consider. This room allows you to expand your barracks and increase the maximum number of heroes you can have in your army.

As you progress through the game and acquire more heroes, you’ll quickly find that your barracks can become overcrowded. By upgrading the Tactics Room, you can alleviate this issue and ensure that you have enough space to accommodate all the heroes you want to use in battle.

Armory for weapon refining

The Armory is an essential castle upgrade that enables you to refine your weapons and improve their stats. In Fire Emblem Heroes, having powerful weapons can make a significant difference in battle. By upgrading your Armory, you gain access to weapon refinement options that can enhance the might, accuracy, and other attributes of your weapons.

This upgrade is particularly useful for optimizing your team’s overall strength and increasing your chances of victory in challenging battles.

When it comes to castle upgrades in Fire Emblem Heroes, these gameplay-related enhancements are among the top choices for players looking to improve their overall performance. By investing in orb structures for summoning heroes, expanding your barracks with the Tactics Room, and refining your weapons at the Armory, you’ll be well on your way to building a formidable army capable of conquering any challenge that comes your way.

Upgrades for Resources and XP

One of the key aspects of castle management in Fire Emblem Heroes is upgrading your resource-producing buildings and facilities to maximize your gains. These upgrades not only provide you with more resources but also boost your experience points (XP) and shard bonuses.

Let’s delve into the different ways you can upgrade these vital aspects of your castle.

Upgrading resource-producing buildings

Resource-producing buildings are essential for maintaining a steady supply of valuable items and currency in Fire Emblem Heroes. To upgrade these buildings, you’ll need to invest a certain amount of resources and time.

Each upgrade level increases the production output, allowing you to collect more resources for your heroes and castle development. It’s a great idea to prioritize upgrading these buildings to ensure a steady flow of resources.

One popular resource-producing building is the Crystal Mine, which produces crystals used for summoning heroes. By upgrading the Crystal Mine, you can increase the number of crystals you obtain per hour, giving you more chances to summon powerful heroes for your team.

Additionally, upgrading the Dueling Crest Tower will grant you more dueling crests, which are necessary for participating in the Arena and earning precious rewards.

XP and Shard bonuses from facilities

Facilities in your castle not only provide valuable resources but also offer XP and shard bonuses to help level up your heroes. Upgrading these facilities is crucial for maximizing your hero’s potential and strengthening your team. Here are some notable facilities that offer XP and shard bonuses:

  1. The Training Tower is a facility where you can send your heroes to gain XP and level up. Upgrading the Training Tower increases the amount of XP your heroes receive, making it easier to train them to their full potential and unlock new skills.
  2. The Tempest Trials Bonus facility grants bonus XP and shard rewards during the Tempest Trials event. Upgrading this facility increases the bonuses, allowing you to earn more rewards and strengthen your heroes faster.

By upgrading these facilities, you can accelerate the growth of your heroes and unlock their true potential in battle. Don’t underestimate the power of upgrading; it can make a significant difference in your Fire Emblem Heroes gameplay experience.

Optimizing Your Upgrade Order and Strategy

Focus on the most beneficial upgrades first

When it comes to upgrading your castles in Fire Emblem Heroes, it’s important to prioritize which upgrades will bring the most value to your team. Consider focusing on upgrades that directly impact your heroes’ stats, such as the Training Tower or the Hero’s Path.

These upgrades can provide your heroes with additional experience points, skills, and overall growth, allowing them to become stronger and more effective in battle.

Additionally, don’t forget to invest in upgrades that provide resources and rewards, such as the Aether Keep or the Aether Resort. These upgrades can grant you valuable items, currency, and even special events that can further enhance your gameplay experience.

By focusing on the most beneficial upgrades first, you can ensure that your castle is optimized for maximum efficiency.

Balance short and long-term upgrades

While it’s tempting to prioritize immediate upgrades that provide instant benefits, it’s crucial to also consider the long-term impact of your upgrade choices. Some upgrades may take longer to complete but can significantly boost your overall progress in the game.

For example, upgrading the Castle Walls can increase your defense against enemy attacks, while upgrading the Castle Treasury can increase your resource storage capacity.

By balancing short-term and long-term upgrades, you can create a castle that is not only strong in the present but also well-prepared for future challenges. Consider creating a plan or a checklist to help you stay organized and ensure that you are making progress towards both immediate and long-term goals.

Maximize facility adjacency bonuses

One often overlooked aspect of castle upgrades is the facility adjacency bonuses. Some upgrades provide additional benefits when placed adjacent to certain facilities. For example, upgrading the Training Tower next to the Hero’s Path can grant your heroes even more experience points.

To maximize these bonuses, carefully plan the placement of your upgraded facilities. Consider consulting online resources or forums for optimal placement strategies. By strategically arranging your facilities, you can take full advantage of the adjacency bonuses and boost the overall effectiveness of your castle.


Upgrading your castle in Fire Emblem Heroes not only makes your fortress look nicer, but also unlocks vital gameplay benefits. Use this guide to understand the most strategic upgrades to pursue for orb summoning, expanding your barracks and teams, weapon forging, and more.

By planning your castle development and optimizing your upgrade order, you can maximize your heroes’ strength and enjoy all the perks the game has to offer. Prioritize the upgrades that improve your gameplay experience first before the purely aesthetic ones.
